I wanted to introduce my project bringing colors to the DMDs in your cabinet.It uses chinese 2.5 dot pitch RGB DMDs driven by a STM32F407 developer board.It has a USB interface which uses the open pindmd protocol as documented in thepinMAME source. Therefore should work with all other pindmdv2 compatible applications.Alternatively it has a input for real pinball machines using the 14pin DMD interface connector.It supports colorized Stern ROMs an custom palette upload. The project is completely open sourceand is published on github https://github.com/lucky01/PIN2DMD
